Atmospheric dimethylsulfoxide (DMSO), an important dimethylsulfide (DMS) oxidation by-product, has been monitored on a daily basis at Amsterdam Island in the southern

The estimates of PfRc were generated by the Malaria Atlas Project using a malaria transmission model to describe the relationship between PfRc and the predicted probability

For some classes of polycrystalline materials, the concepts of 3D X-ray diffraction microscopy and tomographic imaging can be merged: the combined methodology, termed X-ray

A pure elastic behavior of the crystal is observed : a linear strain profile develops on tensile components while shear and rotation components remain identical to the initial

In the first phase (1), up to 60% of the maximum stress, many events of small amplitude and low energy occur (figure 4.a). These events are linked to fibre break. Over a load of

This paper focuses on identifying aerosol plumes in the MCMA basin during the MILAGRO field campaign using High Spectral Resolution Lidar (HSRL) measurements (Hair et al., 2008)

Among them, four organizational requirements are considered to be relatively unique to high-speed maglev systems, and particularly significant: (1) Advanced
